WATCH: Exclusive Clip from Johnny Cash Documentary ‘My Father and the Man in Black’

Exclusive Look at Jonathan Holiff's New Johnny Cash Documentary

After his father committed suicide, Jonathan Holiff discovered an incredible secret in a storage locker: recordings of the elder Holiff’s audio diary from his days as Johnny Cash’s manager from 1960 to 1973.

In his new film, “My Father and the Man in Black,” Holiff combines found footage, re-enactments and his own voice-over narration to craft a story about the father he hadn’t spoken to for two decades–and about the often-troubled music legend who turned to religion for solace.

In the clip below, provided exclusively to TOH!, Jonathan listens to his father Saul’s diary recording of one remarkable morning in Toronto, when he and others found Cash passed out on the floor of his RV from an overdose. “For all intents and purposes, he was dead,” says Saul.

A few hours later, Cash performed two sold-out shows in Rochester, New York, as if nothing had happened.
